High-Purity Antimony Ingot (Sb 99.9% min)

These are refined antimony ingots at a minimum content of Sb 99.9%, with the bright silvery-white surface of the refined metal. Antimony occupies a narrow but difficult-to-substitute position in industry: it is metallurgically a hardening agent, and chemically a key component of flame retardant systems.

Its largest single use is as an alloying addition to lead in battery grids, where a small percentage of antimony markedly improves the mechanical strength and castability of the lead. In flame retardants it works as a synergist, dramatically raising the effectiveness of halogenated compounds. In both cases the addition is measured in small percentages, so consistency of the base metal matters more than the absolute purity number.

Refined antimony ingots are consumed in:

• Lead-antimony alloys for battery grids and plates
• Flame retardant systems as a synergist
• Bearing metals and low-friction alloys
• Ceramics, enamels and glass clarification
• Semiconductor and specialty metallurgical use

State the alloy or system the antimony is going into. A battery alloy producer will care about the arsenic and lead content of the base metal because those carry into the grid alloy; a flame retardant producer will care about particle size and oxidation once the metal is converted, which is a downstream consideration rather than a property of the ingot itself.

For an enquiry, include the tonnage, the ingot weight your handling equipment accepts, the packing form and the destination port. If your market regulates antimony content in the finished product, mention that at quotation stage so the lot analysis can be checked against it.

Ingots are stacked and strapped in bundles, palletised, or loaded loose according to your handling method. Packing is matched to the unloading equipment you have, and the packed weight is confirmed before the container is sealed.

Every lot ships with a certificate of analysis stating the full chemical composition, produced under an ISO 9001:2015 quality management system. That is more than the headline purity figure: it is the residual elements that decide whether two lots at the same stated purity behave the same way in your process.

You can nominate an independent inspection agency — SGS and BV are the two we handle most often — for pre-shipment sampling, weight verification and container sealing. The report is issued to you rather than to us, and you are equally welcome to send your own representative.

Standard export documentation covers the commercial invoice, packing list, certificate of origin and bill of lading, alongside the chemical composition report. If your market requires an additional declaration, tell us at quotation stage rather than after the container is sealed. See the terms of service for how inspection and claims are handled.
